ADVERTISING DEVICE.

Specification of Letters Patent.

Patented April 17, 1906.

Application filed May 10,1905- Serial No. 259,785

T0 at whom it may concern:

Be it known that I, HERCULES A. DE RU- DIO, a citizen of the United States, and a resident of Los Angeles, in the county of Los Angeles and State of California, have invented a new and Improved Advertising Device, of which the following is a full, clear, and exact description.

This invention relates to advertising by the use of signs. It is especially useful in connection with street-car advertising.

The object of the invention is to produce a device of simple construction which will contain a plurality of signs or cards carried upon a web, such that these signs may be periodically brought into View.

- The invention has the effect of increasing the available advertising-space.

The invention consists in the construction and combination of parts, to be more fully described hereinafter and definitely set forth in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a front elevation of the central portion of the device, a portion of the web of signs being represented as broken away so as to expose the inner construction. Other portions are shown in section and broken away, as will appear. Fig. 2 is substantially a plan view of the construction shown in Fig. 1. Fig. 3 is a plan View of the central portion of the bottom-of the case of the device, the ends of the same being represented as broken away.

Fig. 4 is a plan view showing a portion of the upper face of the bottom of the case and illustrating the means for guiding the web. Fig. 5 is a cross-section taken substantially on the line 5 5 of Fig. 4 and upon an enlarged scale. Fig. 6 is a front elevation showing a chain which constitutes a portion of the web and illustrating the manner inwhich the advertising-cards are attached, and Fig. 7 is a perspective view showing a short portion of the chain illustrated in Fig. 6.

Referring more particularly to the parts, 1 represents a casing comprising an elongated bottom board or bottom 2 and a similar elongated upper board or cover 3. These boards have the same general outline, as indicated from a comparison of Figs. 2 and 3, and are connected rigidly by end pieces, such as the end piece 4. (Indicated in Fig. 4.) The lower side of the upper board and the upper side of the lower board 2 are similarly constructed. The construction of the lower board or bottom 2 of the casing will now be described, referring especially to Figs. 3 and 4. At its central portion this board expands in width, so as to form a body 5, the forward edges 6 whereof incline slightly rearwardly, as indicated. The upper face of this body is formed with a recess 7, as indicated in Fig. 3, in such a manner as to leave an upwardlyprojecting bead 8 at the forward side of the board and a similar bead 9 at the rear edge of the board. The extremities of the board or bottom 2 are of uniform width and project outwardly, so as to form integral arms 10. The extremities of these arms 10 are united by the end pieces 4 in the manner suggested above. The arms 10 are preferably of uniform width, as indicated. At their outer extremities the arms 10 are formed with recesses 11, as indicated in Fig. 4. The entire upper faces of the arms 10 are formed with longitudinally-disposed channels or grooves 12, as indicated most clearly in Fig. 5, said grooves being formed with contracted openings or slots 13 and enlarged below, as also indicated in Fig. 5. Slots of this general form are technically known as T-slots, and their purpose will appear more fully hereinafter. There are preferably four of these channels or grooves 12, as shown. These grooves pass continuously from end to end of the arms connecting the recesses 11 and 7, as will be readily understood.

In the bead 9 at the rear edge of the board a longitudinally-disposed groove or channel 14 is formed, which channel is extended at its extremities, so as to open communication between the end recesses 11 at the extremities of the board, as will be readily understood. This channel is substantially similar in form to the channels 12, as will appear from an inspection of Fig. 5.

In the bead 8 at the forward edge of the board a channel or groove 15is formed, which passes longitudinally in the bead, as indicated. This channel or groove 15 is extended into the arms 10, lying at these points substantially parallel with the aforesaid grooves 12. These extensions of the channel 15 pass to the recesses 11, as indicated in Fig. 4.

As indicated most clearly in Fig. 1, in the space inclosed by the casing a motor 16 is mounted, said motor operating to drive a counter-shaft 17 in any suitable manner, as shown. This counter-shaft is provided at its extremities with worms 18. meshing with worm-wheels 19, carried by vertical shafts 20. As indicated, these shafts 20 are stepped in the bottom 2 of the casing and carry rigidly at their upper extremities gear-wheels 21. As indicated most clearly in Fig. 2, these gear-wheels 21 are disposed in enlarged recesses 22, formed in the upper face of the upper board 3, and in these recesses pinions 23 are mounted, the same being carried by vertical shafts 24, stepped upon the bottom board 2, as indicated. These shafts are provided near the inner faces of the top and bottom boards with sprocket wheels 25, as shown most clearly in Fig. 3. From an inspection of this figure it will be seen that the shafts 24, just referred to, are arranged in alinement with the channels 12 in such a way that a chain or web passing about the sprocket-wheels could be guided in and out of the channels in a well-understood manner.

At the extremities of the arms are provided vertical shafts 26, there being three of these shafts in connection with each arm. Upon these shafts are loosely mounted sprocket-wheels 27 as indicated in Fig. 4. The shafts 26 are located between the channels 12, so that the sprocketwheels 27 operate to guide a web in and out of the channels in a well-understood manner. Thus it will be seen that the sprocket-Wheels 25 are located near the inner extremities of the channels 12, while the sprocket-wheels 2 7 are located at the outer extremities. Furthermore, the two sprocket-wheels 25 on each side are arranged intermediatelywithrespect to the sprocket-wheels 27, from which arrangement it becomes possible to guide a web with these sprocket-wheels, so that it would pass inwardly in the channel 12, returning outwardly in the channel 12 This web would then be guided inwardly in the channel 12' and outwardly again in the channel 12.

The web (indicated at 28 in Fig. 1 and which includes the advertising-cards) will now be described. This Web comprises also a pair of continuous chains 29, which pass from end to end of the device in the channels 14 and 15. At the extremities of the arms the courses of the chains which lie in the channels 14 and pass into the channels 12 of the arms in a manner as described, being guided about the sprocket-wheels and 27, as will be readily understood.

As indicated in Fig. 7, the chain is composed of links 30, presenting transverse bars 31 and enlarged eyes 32, the links having substantially the form of a U, as Will be readily understood. The chain is applied to the grooves in the manner indicated in Fig. 5, so that the bars 31 of the links pass upwardly through the contracted openings or slots 13, referred to above. The enlarged eyes, which lie in the enlarged portion of the grooves, prevent the chain from being pulled out of the groove, as will be readily understood.

As indicated in Fig. 1, to the projecting edges of the chains 29 binding strips or tapes 33 are attached, and to these tapes advertising-cards, such as the card 34, are attached, as indicated in Fig. 6, by means of fasteners 35 of a common form used in attaching papers together. On account of this arrangement for attaching the cards to the chains the cards may be readily removed and replaced by others when desired.

With the arrangement described the chains 29, connected, as they are, by the signs or cards, constitute a continuous web, the principal portion of which will be taken up in passing through the guiding-channels 12 in the arms. However, the forward face of the web would be presented to view, and the signs exhibited in this way are constantly being changed by the progressive movement caused by the motor 16.

In connection with the operation of the device it should be understood that the rotation of the counter-shaft 17 operates through the worms 18 to rotate the shafts 20 in the same direction. The shafts 24, it will be remembered, carry the pinions 23, which mesh with the gear-wheels 21. From this arrangement the shafts 24 are all driven in the same direction, and they operate through the medium of their sprocket-wheels 25 to advance the chains 29, which pass around them, as indicated.

It will be apparent that a web of relatively great length can be used in a device of this construction, and by the operation of the machinery all portions of the web will be successively exposed to view. In this way the device has the effect of increasing the avail able advertising-space at a point where it is set up.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a device of the class described in com bination, a guide presenting a groove with a contracted opening, a chain adapted to move in said groove and having a transverse bar pro ecting upwardly through said contracted opening, and means for attaching advertising matter to said chain.

2. In a device of the class described in combination, a pair of oppositely-disposed guiding-walls having T-slots on the adjacent faces thereof, chains guided in said slots and having enlarged portions afiording means for retaining said chains within said slots, and means for attaching advertising-cards between said chains.

3. In a device of the class described in combination, a guiding member having a T-slot in the face thereof, and a chain having en larged eyes disposed in the enlarged portion of said slot and having bars projecting outwardly from said face.

4. In a device of the class described in combination, a casing comprising an upper board and a lower board, said boards having guidegrooves in the forward and rear edges thereof, said boards further having a plurality of guide-grooves extending inwardly from the extremities thereof, transverse shafts connected with said boards, sprocket-wheels mounted on said shafts, chains passing around said sprocket-wheels and having enlarged extensions lying within said grooves, means for advancing said chains, and means for attaching advertising matter between 15 HERCULES A.
